Hello all,
I have ceph Luminous setup with filestore and bluestore OSDs. This cluster
was deployed initially as Hammer, than I upgraded it to Jewel and
eventually to Luminous. It’s heterogenous, we have SSDs, SAS 15K and 7.2K
HDDs in it (see crush map attached). Earlier I converted 7.2K HDD from
filestore to bluestore without any problem. After converting two SSDs from
filestore to bluestore I ended up the following warning:

The pool I have problem with, has replicas on SSDs and 7.2K HDD with
primary affinity set as 1 for SSD and 0 for HDD.
All clients eventually ceased to operate, recovery speed is 1-2 objects
per minute (which would take more than a week to recover 12500 objects).
Another pool works fine.
How I can speed up recovery process?
Thank you,
Ignaqui
